lizards with long tails are better able to climb trees to catch insect prey that live in the canopy.
decreasing average temperature favors the dark - brown lizards, which absorb more heat.
answer bank
in areas where the ground is covered by light and dark rocks, the medium - brown lizards stand out more than the light - brown or dark - brown lizards.
medium - brown lizards blend in best with the field soil and vegetation, making them harder to spot by predators than the light and dark individuals.

Explanation:

Stabilizing selection favors the intermediate phenotype. Medium - brown lizards blending well with field soil and vegetation (less likely to be spotted by predators) is an example of stabilizing selection as the intermediate color is favored. Directional selection favors one extreme phenotype. Lizards with long tails being better at climbing trees to catch prey is directional selection favoring long - tailed lizards. Disruptive selection favors the extreme phenotypes over the intermediate. In areas with light and dark rocks, medium - brown lizards standing out while light - brown and dark - brown lizards are favored is disruptive selection.

Answer:

Stabilizing: Medium - brown lizards blend in best with the field soil and vegetation, making them harder to spot by predators than the light and dark individuals.
Directional: Lizards with long tails are better able to climb trees to catch insect prey that live in the canopy.
Disruptive: In areas where the ground is covered by light and dark rocks, the medium - brown lizards stand out more than the light - brown or dark - brown lizards.
